    IG_FIP_DST_forward_from_image
    In This Topic

    This function computes the forward Discrete Sine Transform (DST) of the input image.

    Declaration:

     
    Copy Code
    AT_ERRCOUNT ACCUAPI IG_FIP_DST_forward_from_image(
            HIGEAR hIGear, 
            LPHIGCOMPLEXOBJ lphIGComplexObj
    );
    

    Arguments:

    Name Type Description
    hIGear HIGEAR HIGEAR handle of image to be processed.
    lphIGComplexObj LPHIGCOMPLEXOBJ HIGCOMPLEXOBJ handle of result data.

    Return Value:

    Returns the number of ImageGear errors that occurred during this function call.

    Supported Raster Image Formats:

    Grayscale - 8, 16, 32 bpp.

    Sample:

    FreqIP

    Example:

     
    Copy Code
    HIGEAR hIGear;                           /* HIGEAR handle of input image */
    HIGCOMPLEXOBJ hIGComplexObjOut; /* HIGCOMPLEXOBJ handle of output data */
    ...
    IG_FIP_DST_forward_from_image(hIGear, &hIGComplexObjOut);
    ...
    

    Remarks:

    The difference between this function and IG_FIP_DST_forward() is that this function takes a HIGEAR as the input.
